Swallow test

There are two methods of the swallowing test method. The first is to place the olive head of the auscultation tube on the external auditory canal of the patient and the examiner, and then ask the patient to swallow and judge whether the eustachian tube function is normal according to auscultation. The second method is to ask the patient to swallow and observe the tympanic membrane. If the tympanic membrane can move outward with swallowing, it shows that the function is normal.
